A.2 - Mar., 2015 APX9172/72A/72B www.anpec.com.tw7 Function Description Output Switch Principle The APX9172/72A/72B built in a Hall-effect sensor plane to sense the vertical magnetic flux density (B). There are two output drivers in APX9172/72A/72B to drive single- phase DC brushless motor. For example of TSOT/23-6 package, when the N pole magnetic field close to the IC marking surface and the magnetic flux density higher than operate point (Bop), the OUT1 pin output will turn to LOW and the OUT2 pin output will turn to HIGH. When the N pole magnetic field far away the IC marking surface and S pole magnetic field close to the IC marking surface until the magnetic flux density higher than release point (Brp), the OUT1 pin output will turn HIGH and the OUT2 pin output will turn LOW. Lockup Protection and Automatic Restart The APX9172/72A/72B detects the rotation of the motor by internal hall sensor signal, and adjusts lock detection ON time (TON) and lock detection OFF time (TOFF) by inter- nal counter. Speed Control by Direct PWM Input Signal Applying PWM pulses to the PWM pin directly, the duty cycle of PWM pulses will control the output driver ON duty directly. In PWM control, the high level of pulse signal should be higher than 2.5V and the low level should be lower than 0.8V. When the PWM pin is floating, the output driver of APX9172 /72A/72B will be full duty to drive the motor. Lock OUT1 FG Release Reset TOFF TON OUT2 B=0 Lock Detection TOFF RD Quick Start and Standby Mode This IC would enter standby mode when the PWM input keeps low level for then 66.5m(typ.). In standby mode, it will shutdown amplifier and FG. In standby mode, the lock protection function doesn’t work, therefore, starting fan is unobstructed when releasing standby mode. 66.5ms (typ.) disableenable enable PWM Lock protect enable (internal) S N Marking Surface Marking Surface Bop Brp B VOUT1 Bop B VOUT1 Brp B VOUT2 Bop B VOUT2 Brp Bhys Bhys Bop BopBrp Brp S N N S N S (TSOT-23-6) (TSOT-23-6) (SOP-8F) (SOP-8F) Marking Surface Marking Surface
